For every process, identification of risk and protection is essential therefore, to ensure safety and regulatory compliance, operators must develop and implement feasible protection schemes for e-hazards at workplace...By Rajesh Chourishi
With the pace of government initiatives for development of smart grid, there is need to develop different kinds of switchgear suitable for smart grid operation and that is more compact, reliable, environment friendly and requires minimum installation and commissioning time. By Ashok Upadhyay
Due to the continuous increase of power handling capacity, increase in network voltages, continuous design improvements and operational requirements of switchgear. In this article, short circuit test duty requirements of 12kV circuit breaker are discussed. By Yugal Agrawal
The article sheds light on various intricacies of hybrid HVDC Circuit Breaker.
In-depth analysis on how digitisation helps in improving performance and reliability of switchgears. By Subhajit Roy, Group Editor
WAGO offers uninterruptible power supplies (UPS), buffer modules, redundancy modules and a wide range of electronic circuit breakers (ECBs) as a complete system for seamless upgrades…
The global market is set to witness a significant growth due to the continued growth of construction and developmental activities, increasing access to electricity, and growth of renewable power generation projects…
The smart grid is a self-healing network equipped with dynamic optimization techniques that use real-time measurements to minimize network losses, maintain voltage levels, increase reliability, and improve asset management...
The selection of over-current protection devices such as fuses and circuit breakers is made more complicated when high inrush currents must be tolerated. The over-current protection must react quickly to overload or short circuit faults but must not interrupt the circuit when the (usually harmless) inrush current flows…
As a global technology leader in power management solutions and with a host of new technologies and solutions, Eaton is responding to some of the most critical electrical power management challenges that the country faces today.
If the selection of inappropriate specifications switchgears go unnoticed, it may jeopardize safety of man and machines both. Therefore, utmost care is required, while designing an electrical protective scheme as far as selection of CTs of correct specifications, switchgears, etc is concerned.
Timing measurements on gas-insulated switchgear (GIS) with grounding on both sides.
Given their critical role in substation automation, the scope of switchgear is also expected to grow considerably in the near future. Given the government’s reform initiatives, the switchgear market is likely to continue on its growth trajectory.
Retrofitting old medium voltage switchgear with newer technology is an efficient, cost effective and economical option for preserving existing assets, thus, saving cost and time. In the race of implementation and adaptation of new technology we just destroy existing installation by scraping the products for want of alternate solutions and technologically sound and reliable supplier… - Paresh Shah, N P Jhaveri
In this article a basic duty of a “Controlled Switching Device” in back to back switching of a shunt capacitor banks has been explained. The Transients developed are very high in nature and are very injurious to the circuit breaker used for this duty. A case study, highlighting the need for implementing such device for back to back switching of shunt capacitor banks is also described... - Er K K Murty
The work presents the research of high voltage circuit breakers characteristics influence on switching over-voltages and over-currents conditioned by inductive and capacitive load's Switchings. The suggestion for the circuit breakers choice from the point of view of permissible levels of voltages and induced Electro-motive Force in secondary circuits are given... - Amol Sonawane
“Circuit breakers are mechanical switching devices, capable of making, carrying and breaking currents under normal circuit conditions – and also making, carrying for a specified time and breaking currents under specified abnormal circuit conditions such as those of a short circuit... - Dr P K Pattanaik
There are attractive possibilities of the combination of SF6 insulation with vacuum interrupters. Another recent suggestion is to use liquid SF6 in a container much like oil… - Prof N S Gorhe
